Reactor Discharge Cooling System for a Fine Chemical Plant
Designed an all-welded plate heat exchanger cooling system for a fine chemical enterprise, cooling reactor discharge from 120C to 38C with 4x850 kW cooling capacity, significantly improving product quality stability.
Flue Gas Waste Heat Recovery Retrofit for 2x220 t/h CFB Boilers
Installed flue-gas-to-water heat recovery units on two 220 t/h CFB boilers for a thermal power cogeneration enterprise. Flue gas temperature reduced from 175C to 82C, saving 6,800 t of standard coal per year with a 1.8-year payback.
Nacelle Cooling System for an Offshore Wind Farm
For offshore wind turbine nacelle cooling, an indirect cooling approach uses a BXB plate heat exchanger to transfer heat between nacelle internal and external air, preventing salt mist and dust from entering the nacelle and ensuring safe, stable turbine operation.
Drying Exhaust Waste Heat Recovery and Reuse System for a Chemical Enterprise
In the drying sections of chemical, pharmaceutical and food industries, high-temperature exhaust emits substantial heat. A BXB plate heat exchanger recovers exhaust waste heat to preheat fresh air, significantly reducing drying heating energy.
Heat Recovery System for Operating Room Cleanroom HVAC in a Tertiary Hospital
For medical clean areas such as hospital operating rooms and ICUs, a liquid-circulation energy recovery method recovers exhaust cooling or heating while preventing cross-contamination between fresh and exhaust air, reducing cleanroom HVAC fresh-air energy consumption.
Comprehensive Waste Heat Utilization from Stenter Exhaust for a Textile Dyeing Enterprise
Installed finned-tube heat recovery units on the exhaust ducts of 6 stenters, recovering waste heat from 200C exhaust to heat fresh air, saving 1.55 million Nm3 of natural gas per year, while lowering exhaust temperature to facilitate downstream VOCs treatment.
Tunnel Kiln Flue Gas Waste Heat Utilization for a New Building Materials Enterprise
Installed a tubular air preheater in the tunnel kiln flue, using 280C flue gas waste heat to preheat combustion air to 180C, saving about 12% fuel, 2,100 t standard coal per year, 1.5-year payback.
